    Just do

    Code:
    try {
  hunger = Integer.parseInt(args[2]);
} catch (NumberFormatException e) {
  // Code for Invalid Input
}
    Some say this is an invalid use of trycatch blocks, but it's actually completely OK to use TryCatch blocks to determine and or filter data in this fashion. That's not to give you the impression of just stuffing all of your data analysis into a try catch block.
